Outline

In a prospective study the results of the aRM and RRM in the preoperative diagnostics of patients with nasal obstruction were compared to evaluate if there is a correlation between them.

In 50 patients with the symptom of nasal obstruction we compared different parameters of both methods before and after application of a vasoconstrictor (Xylometazolin).

The minimal cross sectional areas MCA1 and MCA2 and the volumina VOL1 (0–2.2 cm from the nostril) and VOL2 (2.2–5.4 cm) were compared with the flow and resistance at a pressure of 75 PA measured by RRM.

In our study wecould not find a significant correlation between the parameters of aRM and RRM before and after application of a vasoconstrictor.

We conclude that none of the two methods can be used as a standalone method in the preoperative diagnostics before rhinosurgery. But both can propably support the indication proposed by clinical examination and medical history. In the future it should be evaluated which of the methods has a better correlation with the patients sensation of nasal obstruction.
